This is my coin slide operated jelly bean dispenser. This started out just wanting to try printing some worm gears I found on Mc-master and I happen to be eating some jelly beans at the time and though "I bet I can make a candy machine that incorporated these gears." I designed up the simple base with the gears and then it snow balled from there when I though "I bet I could also make this coin operated too" (yeah I think out loud ) I know a printed coin operated candy machine has been done already so I decided to try and do a coin slide version.

The dispensing part with the worm gears turned out to be pretty easy to design (especially since I didn't have to design the actual gears) and the base was pretty simple I just had to match threads on the container the jelly beans came in.

The coin slide mechanism took a bit of doing to get all the inner locks working right though. I wanted it to work so you just couldn't slide the coin in and just keep turning the handle till you got all the goodies. The inner working of the coin slide can be seen here if your interested.

This is the exploded view of the entire machine. This was one of my most ambitious prints to date. The base alone took 16+ hours to print. It works pretty well for being 99% plastic. It can jam up with a odd shaped jelly bean though but overall I'm happy with how it came out it was fun project to design.

This is one of those projects that makes me realize how much 3d printing has changed my life I've always loved to make things and constantly have these crazy ideas and the M2 is allowing me to make them happen now... I olny wish this technology was around 30 years ago.
